REED FOB NET-MAKING MACHINES.

Application filed March 28, 1927, Serial No. 179,102, and in Japan April 2, 1926.

This invention relates to improvements in reeds for net-making machines of the type in which the knotless netting fabric, such as may be used for fishing and other purposes, are made, and has for its object to provide a reed, simple in construction and eflicient in operation, for converging the strands for the netting within limited small spaces in proper position for interlocking operation.

The accompanying drawings illustrate a part of the net-making machine with the reed according. to the invention applied thereto, and in which Fig. 1 is a plan view, a portion of the reed being broken away, showing certain means for driving the reed.

Fig. 2 is a perspective view.

Fig. 3 is an enlarged detail view of the driving connection of the reed.

In order to insure a clear and accurate understanding of my reed and method of employing it, I will illustrate and describe an outline of the construction of a machine of the type in which my reed is designed to be applied, by way of example. In Fig. 2, 1 is reciprocating plate and 2 is a stationary plate, which form an upper work ing platform. Directly below said upper working platform is provided a lower working platform identical therewith, the recipprocating plate 6 of which is connected to the reciprocating plate 2, so as to be laterally reciprocated together. The construction of the working platforms will be described herein merely of the upper working platform, as the lower working platform is substantially of the same construction. The working platform is formed with a series of working grooves 3, which consists of three circular holes formed in series so as to somewhat overlap the adjacent hole, the intermediate hole being located to equally extend across the abutting edges of said plates, and receives four working heads 7 of a cross section form of double convex lens in general outline for carrying the spool-s or strand carriers 8 and three cam rollers i having opposite concave surfaces a and convex surfaces 6 in general outline for effecting round motion of said working heads. Said cam roller is supported by a bar 5 extending down to the reciprocating plate 6 of the lower working platform. In order to permit lateral movement of the reciprocating plate 1, the cam rollers in an intermediate row are made in two halves, instead of being formed in one piece. With the arrangement of the parts as described above, each pair of the strands upwardly extending from the strand carriers 8 carried by the working heads 7 are intertwisted by rotation of the side rollers l and consequent rounding motion of each pair of said working heads. Thus, after each pair of the strands has been intertwisted through a certain length, all the Working heads are stopped in the aligned position. Then each pair of the strands or the working heads in two rows at inner side are caused to cross with each other by turning the intermediate rollers 180 degrees in a direction. Then the side rollers are turned 360 degrees in reverse direct-ion and each pair of the strands is caused to intertwist one turn. Then the intermediate rollers are turned again 180 degrees in the same direction as before, and now the intertwisting operation for the strands is to be resumed. Thus the interlock ing operation for the strands is accomplished. The parts so far described, of course, form no part of the invention.

The reed embodying the invention is composed of two plate members 9 and 10, which are mounted on the overhead positions corresponding to the reciprocating plate 1 and stationary plate 2 respectively, substantially flush and in close contact edge to edge with each other, so as to be adapted to be moved by suitable means. The plate member 9 is reciprocated through a length corresponding to one and a half central distance between adjacent working grooves, and the plate member 10 is reciprocated through a length corresponding to a half central distance between adjacent working grooves. The plate members 9 and 10 are provided with a series of notches 11 and 12, regularly spaced along the abutting side edge thereof respectively,

through which notches the strands pass. The notches 11 in the plate member 9 serve to shift the strands to the proper position for interlocking the strands by hooking the same in one of the ends thereof. The notches 12 in the plate member 10 serve to form confined spaces for the strands upon the interlocking operationof the strands in cooperation with the notches 11, the same being moved in the contrary direction to the movement of the notches 11.

'plate member-10 is connected through, a conago,

In *operation; the plate *member i) moves to a direction" through the aforesaid length, hooking the strands, While the plate member 10' moves who 1 the opposite direction through the aforesaid length, and the both plates rest on the proper interlocking position as shown in Fig. 2, providing theispaces for the strands, so confined as to converge the same, during the interlocking;operation.

The movement of the reed may be effected 'by any-suitable means, and=5-in Figs. 1 and3 the means are illustrated by Way of example in "'WhiClI-a lever 13*is pivoted -on=the :ma chine "frame' l near 'its'one end. "Tothe one end of the lever 13-near' the pivot 14 the necting link 15,-and-to the=other-endthe plate member 9 and an-eccentric 16 mounted on a driving shaft l'7rare connected through connecting links 18 and I9"respective ly,:the ec-centricibeingzadapted tozbe intermittently rot-ate'diby suitable means.
